It is somewhat faster and doesn't require a C# runtime - Installing the <i>mono</i> C# runtime on OS X has proved to be problematic on some systems.
</p><p>Additionally, autopano-sift-C has experimental modifications to perform feature identification in conformal image space, this helps with wide angle or <a href="Fisheye_Projection.html" title="Fisheye Projection">fisheye Projection</a> photographs.
</p><p>autopano-sift-C is available from the <a href="Hugin.html" title="Hugin">hugin</a> project and can only be used within hugin as an optional installation due to patent issues: the use of the Scale-invariant feature transform<a class="external" href="http://www.wikipedia.org/wiki/SIFT">[*]</a> algorithm is restricted by US Patent 6,711,293, awarded March 23, 2004 to the University of British Columbia.
</p><p>The current version 2.5.1 (autopano-sift-C-2.5.1) is available since the release of hugin 0.7 in October 2008.

<p>On Mac OS X, autopano-sift-c can be installed via <a rel="nofollow" class="external text" href="http://www.macports.org/">MacPorts</a>:
</p>
<pre>$ sudo port install autopano-sift-c
</pre>
<p>This may take some minutes to fetch and compile the required software. Once complete, the <tt>autopano-sift-c</tt> binary will be installed in <tt>/opt/local/bin</tt>.
</p><p>To get <a href="Hugin.html" title="Hugin">Hugin</a> to use it, you may need to add this full path into the preferences:
</p><p><img alt="Autopano-prefs.png" src="Autopano-prefs.png" decoding="async" width="719" height="258" />
</p><p>Now you're ready to use the control point alignment assistant in Hugin. Load up your images, then hit the 'Align' button:
</p>
<dl><dd><img alt="Autopano-align.png" src="Autopano-align.png" decoding="async" width="304" height="72" /></dd></dl>
<p>At this point you'll either see a big fat error dialog, or if everything's working you'll see a dialog like this while autopano-sift-c does its thing. This may take a few minutes...
</p><p><img alt="Autopano-searching.png" src="Autopano-searching.png" decoding="async" width="720" height="480" />
</p><p>When it's done, Hugin's panorama preview should show you something decent now!
</p><p><img alt="Autopano-done.png" src="700px-Autopano-done.png" decoding="async" width="700" height="368" />
</p><p>You'll probably still want to nudge some things or run the exposure optimizer, but this'll have saved a lot of time manually setting control points.
